China has confirmed that it will launch its 
national emissions trading scheme.
In a 
joint US-China climate statement,   issued as part of President Xi Jinping’s state visit to the United   States, China confirmed that its new trading sytem will cover “key   industry sectors such as iron and steel, power generation, chemicals,   building materials, paper-making, and nonferrous metals”.

Xi Jinping is scoring a propaganda coup by announcing China’s   intention to introduce a national cap-and-trade scheme in 2017, while he   is a guest of Obama at the White House. It will not be lost on   observers that China will be introducing the very kind of scheme that   failed to get through the US Congress, passing the House but being 
defeated in the Senate.
How interesting that China the communist country is introducing the   kind of market-based emissions trading scheme that the United States was   unable to launch.
There are two further points to make. The first is that China is   introducing its national scheme after trying out various options as   local and city-level experimental schemes over the past couple of years.   In 2012, pilot programs were initiated in seven provinces, and have   been closely monitored since. Here China is teaching the world a lesson   in how to introduce reform: first try it out at a small scale in a   variety of forms, and then scale up the most successful.
Second, China is not relying on these market-led cap-and-trade   initiatives alone. It is also reducing coal consumption in its power   sector through direct state intervention, and has been actively   promoting solar photovoltaic and wind power through state-guided   targeted investment, national planning, and local promotion programs. So   the new scheme will take its place as an initiative that helps to   solidify China’s trajectory towards greening its energy systems – after   direct state action has done the heavy lifting.

China’s greenhouse gas emissions represent a quarter of the global   total. For this reason alone, any tangible progress on Chinese climate   action is encouraging. However, what is more promising is what a Chinese   emissions trading scheme could mean for the world.
To date we have only seen pockets of 
emissions trading across the globe;   most notably the EU has had a scheme since 2004 and a Californian   system has been operating since 2013. Despite concerted efforts, there   has been very little headway in linking regional emissions trading   schemes. This is because carbon credits would become fungible.
So if one market crashes, so do the connected markets. The entire   system is only as strong as the safeguards in the weakest market. The   environmental effectiveness of the entire system is only as credible as   the monitoring and verification in the least stringent scheme.
The EU and the rest of the world will be looking closely at the   integrity and robustness of the Chinese market’s design. If China gets   it right, and can elicit enough buy-in, it could represent a turning   point for climate change.

The announced introduction of China’s national emissions trading   scheme in 2017 places irresistible pressure on Malcolm Turnbull to   revisit the issue of an Australian ETS.
When China joins the European Union (the world’s third biggest   aggregate emitter) and a number of other major emitting countries and   states using cap-and-trade schemes to help cut emissions, some 40% of   total global emissions will be covered by carbon markets.
Tellingly, Chinese President Xi Jinping made his announcement at a   joint White House Press Conference with President Obama. Together they   emphasised how the world’s two largest emitters are now collaborating   closely to tackle global warming. Pressure is building within the US to   create a national integrated scheme on the foundations of its regional   efforts, and other major emitters, like Brazil and Russia, are   contemplating similar measures.
Australia’s Direct Action Plan cannot easily be linked to this   growing global carbon market. Its underfunded “reverse auction” process   cannot acquire sufficient emissions to meet even Australia’s 2020   target. Its “safeguard mechanism” is unlikely to require major   Australian emitters to reduce their emissions significantly. Australia   is now transparently out of step with global trends and, relying only on   current measures, incapable of meeting the tougher mitigation targets   which will be required of it in the near future.

The Chinese government’s announcement of a 2017 national ETS is not   surprising. Since 2011 China has been piloting seven trading schemes in   cities including Beijing and Shanghai, albeit with varying success, and   has been planning for and had foreshadowed a national scheme.
The announcement also builds on last year’s 
US-China bilateral agreement,   which included a pledge from China (for the first time) that its   emissions would peak no later than 2030 – although no mention was made   of the level at which they would peak.
What is surprising is the speed with which the divide between   developed and developing states enshrined in both the UNFCCC and its   Kyoto Protocol has now crumbled. Both developed and developing countries   in Paris in December will now state their climate pledges, or “intended   nationally determined contributions”, including China. These   contributions won’t be negotiated by all the parties – that approach has   long gone. And the legal character of these contributions is uncertain.   But China’s announcement on Friday certainly works in favour of a more   robust agreement.
The climate change problem can’t be addressed without China, the   world’s largest emitter (or indeed India, the third largest). China now   joins the other 75 countries (and the European Union) with frameworks   for limiting emissions, and the 47 countries (plus the EU) that have   carbon pricing.
